SPRING-OILING DEVIGE.

Application at August is, 1922. Serial no. 582,655.

To all whom it may concern:

Be it known that I, WILFRED G. MARTIN, a citizen of the United, States of America, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Spring- Oiling Devices, of which the following is a specification.

My invention relates to sprin oilers and more particularly to a spring 01 er adapted to be used in connection with the formal differential housing of a motor car.

The object of my invention is in the provision of a simple means used in connection with, or adapted to be attached to a difierential housing, whereby the spring, mounted thereunder, is oiled automatically therefrom.

Another object of my invention is in the provision of a simple mechanism for automatically oiling a spring from the difierential housing without the use of auxiliary attachments, this particular structure being adapted for use on new cars.

A further object of my invention is in the provision of an auxiliary means utilizing the same principle, whereby my invention ma be applied to old vehicles.

b till further objects of my invention will appear in the following specification in con nection with the annexed drawings in which: I

Figure 1, is a perspective view of my specific oiler showing its attachment toth conventional difierential housing.

Figure 2, is an enlarged detail partially broken away showing a portion thereof.

Figure 3, is a cross sectional view through the oiling device.

Figure 4, is a cross section of a portion thereof enlarged to show the particular'attachment to the spring member and,

Figure 5, is a perspective showing of my principle of oiling as applied or adapted to be incorporated in a new vehicle.

Referring to the drawings, I have shown generally at A the conventional difierential housing of an automobile which carries therein the difierential gears and an axlefurn ishing drivin means for the wheels, none of the above %eing shown.

In Figure 1, I have illustrated a conventional form of mounting a rear sprin this includes a block 10, surrounding the ideaential housing. The spring 11, 1s swung below this block and is held thereagainst in an immovable position by the yokes or rather old cars. This oiler applied quickly to the difierential housing.

the .nut 19, and bolt 20, in

under side of the sprin clamped between the bloc 10, and plate, 13

by means of the nuts 14, upon the threaded ends of the yoke members 12.

In Figure 5, I have shown a form which includes, in the simplest manner, the principle of my invention. A similar mounting is shown as that in Figure 1. This particu lar form of my invention would be more adaptable to new vehicles inasmuch as the particular steps in this construction of my 011m systemwould best be done before assemb y. This, however, is not absolutely necessary. Y

A ertures 15, in the block 10, lie adjacent simi ar apertures 16, in the lower portion of the differential housin Grooves 17, upon the lower face of the block 10, radiate from the lower ends of the holes 15. These grooves provide means for distributing the 011 which seeps automatically from the inner portion of the difierential housing to the outer edges of the spring, whence it continues out thesides of the spring and oils the respective leaves thereof through their sides. I

The specific form of oiler which I have shown in Figures 1 to 4., is one that may be readily attached to vehicles now in use, or is adapted to be and placed in operative connection therewith by merely making a single opening in the lower portion of said housing.

My specific oiler includes a broken band 18, adapted to fit about the differential housing or rather about the axle portion. thereof. Means for adjustably and fixedly holding this band about the housing is provided in connection with the upstanding lugs 21, on the band 18. Aperture 22, is made in the lower portion of the differential housing, this aperture being adjacent a similar opening in a downwardly protruding portion 23, of the band. A. {deuible connection 2 -1, provides means for carry ing the oil, that automatically seeps the differential housing, to a laterally disposed connecting pipe 25. It may be said here that the movement of the axle within the difierential housing torc'es the oil through the hole 22. Upon the outer ends of the pipe 25, are disposed the oil chambers 26, similar in construction and adapted to lie against the inner face of the spring mem her. The oil chambers 26,v are formed in such manner that a rather, substantial amount of oil may be contained therein. All sides of the chamber are housed exce t the one adjacent the ring as maybe clear y seen in Figures 2 an 4. ThlS face includes a perforated plate adjacent the 011 supply chamber and disposed outwardly thereof and adjacent to said plate is a felt pad 27.

Flexible bands. provide means for fixedly.

positioning the oiling chambers in their respective and operative positions ad acent the inner face of the sprmg.

The operation of my specific o1l1n device is obvious in that the oil from the ifferential housing is fed to the oiling chambers and passing through the perforated plates. maintains the felt member in a saturated condition with the result that a gradual and ellicient, oiling of the respective leaves of the spring is obtained. The 011 appl ed at th s part of the spring due to the actlon of said spring, is gradually carr ed to the outer end thereof, however, 1n a reasonable quantity. 7

I have shown my oiling device as applied to the rear housing of a motor car, however, I do not wish to limit my invention to this particular structure as a similar system may be readily applied to the front axle by mere- 1 supplying a simple 011 reservolr or cup t erefor.

Also, I haveshown no particular dlstributing means in the spring, as my invention is in the manner of feeding oil from the differential to the spring itself. My invent on might readily be used in connection with various means for oiling the springs within themselves, for instance, with those having grooves upon the under sldes of the plates providing'lateral flow of the 011.

1. In a spring oiling device, Including, in combination, a differential and axle housing, a spring member, and means, includ ng connections between the differential housing andspring member, whereby oil in thedifferential is fed, due to the rotary action of the axle therein, to said spring member;

2. In a spring oiling device, including, in combination, a diiferential and axle housing,

a spring disposed thereunder, an oiling block surrounding the differential housing and ing, a sprin member adapted to be swung beneath sai housing by means of a yoke member, oiling chambers engaging the sides of the s ring, and connections between said oiling c ambers and the differential housing, whereby oil is fed therefrom, due to the rota action of the axle contained therein, to said chambers.

4. In an oiling device, including, in combination, a differential and axle housing, a spring disposed thereunder by means of a yoke member, a band surrounding the houslng member and having an aperture therein engaging a similar opening in said housing, oil chambers adapted to lie against the sides of the spring, and oil distributing means gonnecting said band and oil supply chamers.

5. In a spring oiling device, including, in combination, a spring member, a difi'erential axle housing disposed thereabove and having an oil eeding aperture therein, oiling chambers disposed in operative position adjacent the sides of the spring, and oil distributing means between said chambers and the differential housing, adapted to carry the oil, fed through the opening in said housing, due to the rotary action of the axle therein, to the oiling chambers.

6. In a spring oiling device, including, in combination, a differential and axle housing, a spring disposed thereunder,.oiling chambers adapted to lie adjacent the sides of thel spring, said chambers including an oil pad and a perforated plate member thereagalnst, and an oil distributing means connecting said oiling chambers and the differentlal housing.

In testimony whereof I aflix my signature.

WILFRED G. MARTIN.
